Re: How to use [NSURL loadResourceDataNotifyingClient:usingCache:] ?

I implement both -URLHandleResourceDidBeginLoading: and -URLResourceDidBeginLoading: in the client. But they are never called. Does it work in GNUstep ? Or am I doing something wrong ? You are doing something wrong ... 1. The -URLHandleResourceDidBeginLoading: method is sent to the NSURL object, not to its client. So implementing this in the client will have no effect. If you want the method to be called you need to make your object a client of an NSURLHandle rather than an NSURL. 2. The -URLResourceDidBeginLoading: method is not part of the URLClient protocol, so NSURL clients should not and do not get sent a method notifying them when loading starts. This is presumably because the only way to make an object a client of an NSURL is by sending the NSURL instance a -loadReasourceDataNotifyingClient:usingCache: method. ie your code already knows that loading has just begun, so it can tell the client that itsself. I can't think of any other reason why Apple would have decided not to put a method like that in the protocol. ___ Help-gnustep mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/help-gnustep

Thanx a lot. It works perfectly.

I attach a test program. It will run infinitely until the loading is finished. Hope it help. Thanks ... please update from CVS again (I made a typo). Also ... your program needs to run the main runloop while waiting for the URL operation to complete ...
